ABC is a triangular plate of uniform thickness. The sides are in the ratio shown in the figure. I AB – I BC and I CA are the moments of inertia of the plate about AB, BC and CA as axes respectively. Which one of the following relations is correct ?
I AB > IBC
I BC > I AC
I AB + I BC = ICA
I CA is maximum
